    Abstract: A paging system has a signal for transmitting a variable amount of messages to paging receivers. The signal has a synchronization signal (100), an address field (104), an information and a boundary signal indicative of the boundary between the address field and the information field. Each message has an address which is included within the address field and may have message information which is included in the information field. The information field includes two portions, a first portion (106) having a plurality of packets for holding a predetermined amount of information and a second portion (108) for holding a variable amount of information. If the message information is greater than the predetermined amount, it is stored in the second portion of information field and a vector signal indicating the location of the message information is stored in the first information field.
